Pawnsan. 4..

Application filed September 10, 1919. Serial No. 322,811.

To all whom it may concern:

Be it known that I, SHERMAN H. PAX'roN, a citizen of the United. States, residing at St. Paul, Minnesota, have invented certa n new and useful Improvements in Hand Marking or Printing Devices, of which .the following is a specification.

This invention relates to improvements in hand marking or printing devices.

The main objects of this inventon are:

First to provide an improved marking device well adapted for the marking of packages or parcels having yielding and more or less uneven surfaces.

Second, to provide an improved marking device which may be conveniently and rapidly manipulated.

Third, to provide an improved hand mark ing device having a rotating; printing roller which may be operated in either directlon.

Fourth, to provide an improved hand marking device which produces clear imprints and may be operated a large number of times without replenishing the lnk sup- P y- Fifth, to provide animproved hand marking device in which the operative parts are all incased so that they are protected from dust and kept sanitary and the hands of the operator are not likely to come into contact with the ink.

Sixth, to provide an improved marking device in which the parts are simple and economical to produce and assemble, various parts being duplicates, thereby reducing the cost of manufacture.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed outin the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanvino. drawinct. forming a part of this specification, in which:

Figure I is a side view of a hand marking device embodying the features of my invention.

Fig. II is a side view thereof, with one of the end plates of the housing removed, the handle being broken away.

Fig. III is a detail view, mainly in vertiw calcentral section, on a line corresponding to line 3*? of Flgs. I and II.

Fig. IV is a detail section throiigh the inking roller on a line corresponding to line 4-4 of Fig. III.

F ig. V is a detail section through theink- 111g roller on a line corresponding to line 5-5 of Fig. III.

Fig. VI is an enlarged detail section on a line corresponding to line 66 of Fig. II, showing details of the inking rollers.

Fig. VII is a detail section on a line corresponding to line 7-7 of Fig. III, show ing details of the inking roller actuating means. y

In the drawing, similar reference characters refer to similar parts throughout the several views, andthe sectional. views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, I provide a housing consisting of a central body portion 1 and detachable side plates 2. The side plates are duplicates. The parts may be conveniently made as die casting. The body member 1 is shell-like and provided with lugs 3 adapted to receive the side plate attaching screws 4. At its lower end the body member has an opening at 5. At its upper end it has a threaded extension 6. adapted to receive the handle 7. The side plates 2 have opposed bosses 8 toward their upper ends adapted to receive the shaft 9 for the ink supplying roller 10 carrying the inking pad 11. The ink may be supplied to this pad, as required, by removing the handle 7.

At their lower endsv the side plates 2 are provided with opposed bosses 12. into which the printing roller stub spindles 13 are threaded. Between the bosses 8 and 12 the side plates have horizontal otlisets providhorizontal internal channels 14.

The printing roller 1.5 is mounted on: the inner ends of the spindles 13, which have thrust collars 16 supporting the printing roller longitudinally. On the outer sides of these thrust collars are driving members 17, having driving; lugs l8 coacting with the internal driving lugs 19 of the printing roller, the lugs 18 of the driving members being disposed on opposite sidesof the driving lugs 19 of the printing roller, as is clearly shown. in Figs. IV and V.

The driving members 17 are actuated by the coiled springs 20, which are arranged within the barrels 21 provided therefor on the side members, the barrels being concentric with the bosses 12. The outer ends of these springs are engaged through slots 22, see Fig. VII, while their inner ends are engaged with notches 23 in the driving members, see Figs. IV and V. Thus arranged, the springs act oppositely to return the printing roller to its initial position, one spring acting to return it when the roller is rotated in one direction, and the other acting to return it when it is rotated in the opposite direction.

The roller has recesses 24 in its ends which receive the mechanism described, thereby permitting a compact arrangement of the parts. With the parts thus arranged, the roller is yieldingly held in its initial position and may be actuated in either direction by placing it upon the surface to receive the imprint and moving thereon in either direction. As soon as raised from the surface, one or the other of the springs will return the roller to its initial position.

The type shown conventionally at 25 is preferably formed of rubber and I preferably form the resilient annular tread members 26 integral therewith. These resilient tread members 26 are disposed at the ends of the printing roller and serve to support it during its rotation across blank spaces in the type, and also prevent the type being pressed down to such an extent as would produce blurred and irregular imprints. The type is shown as molded in tegral, but it will be understood that type may be inserted, and this is particularly desirable where the device is used as a dating stamp.

The ink is transferred to the printing roller from the supply roller by means of the inking rollers 27, which are arranged oppositely to engage with both the printing and supply roller. These inking rollers are provided with floating shafts 28 connected by the coiled springs 29, so that the rollers are held yieldingly against the printing and supply rollers, and they accommodate themselves to variations or irregularities therein, such as variations in the type, or variations in the inking pad, and other irregularities. The channels of the side plates accommodate these springs 29.

The rollers are provided with disks 30 at their ends, providing flanges which travel on the printing roller on the inside of their treads, the inking rollers being of such length that the flanges lie at the ends of the supply roller. These flanges perform the double purpose of supporting the inking rollers when they travel over the blank spaces in the type, and also guarding the treads so that they do not become covered with ink, in whirh case they would mark the surface receiving the imprint.

The rollers arranged in pairs transfer the ink to the printing roller when it is rotated in either direction, so that in use it is kept properly supplied with ink. This arrangement of parts permits the structure to be made very compact, and, at the same time, the supply and printing rollers may be of substantial dimensions. The supply roller is rotated in operation so that the ink carried thereby is effectively distributed to the inking rollers and by them to the printing roller. The tension of the springs 29 is such that while the inking rollers are held yieldingly in position, they are not held against the inking roller with such stress as to cause them to take an undue supply of ink. The ink can be supplied, as stated, through the top of the housing by removing the handle 7 The casing, as thus formed, is dust proof, the working parts are protected so that the structure is clean and sanitary, and does not smudge or smear the surface on which it is laid. The parts are quite simple and economical to produce, and are designed so that they may be easily assembled and adjusted in use. The structure is strong and capable of withstanding very severe usage.

I have illustrated and described myimprovements in an embodiment or adaptation which I find very practical. I have not attempted to illustrate or describe other adaptations or embodiments, as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody the same as may be desired.
